Abstract (en)
Gingival retracting cords including propylhexedrine (e.g., propylhexedrine HCI) for providing hemostasis and retraction or displacement of gingival tissue. The retraction cords include a hemostatic and tissue stiffening and retraction effective amount of propylhexedrine which avoids the negative side effects associated with the use of epinephrine, commonly used in conventional retraction cords. Retraction cords incorporating propylhexedrine do not cause increased blood pressure or accelerated heart rate. In addition, such retraction cords may include astringents, such as iron (III) salts without causing discoloration of the retraction cord, the patient's teeth or gums, or the fingers of the dental practitioner, as would occur if one were to blend epinephrine with iron (III) salts. Water or other appropriate solvents may be used to impregnate, or otherwise treat, the retraction cord with propylhexedrine (e.g., propylhexedrine HCI). <IMAGE>
